Bis-(2,6-dichlor-benzyl)-trisulfid, also known as 1,2-bis(2,6-dichlorobenzyl)-1,2,3-trithiane, is an organosulfur compound with the chemical formula C14H10Cl4S3. It is a white crystalline solid that is insoluble in water but soluble in organic solvents. Bis-(2,6-dichlor-benzyl)-trisulfid is primarily used as a vulcanization accelerator in the rubber industry, enhancing the speed and efficiency of the vulcanization process. It is also known for its ability to improve the physical properties of rubber, such as its resistance to heat, aging, and ozone. Bis-(2,6-dichlor-benzyl)-trisulfid is synthesized through the reaction of 2,6-dichlorobenzyl chloride with sodium sulfide in a polar solvent. Due to its potential health and environmental risks, it is important to handle this chemical with care and in accordance with safety regulations.
The CAS Registry Mumber 5219-71-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,1 and 9 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 5219-71: (6*5)+(5*2)+(4*1)+(3*9)+(2*7)+(1*1)=86 86 % 10 = 6 So 5219-71-6 is a valid CAS Registry Number.
